To je pozoruhodny priklad demagogie. Classless delegace nejsou vubec
work-around na nesikovnost zonoveho formatu, nybrz na nesikovnost
reverzniho resolvovani jako takoveho.

OK, diky za informaci.

Ale jak se tak prokousavam strankami o djbdns, cim dal tim vic mi vadi,
ze polovina z toho je neprilis pravdiva propaganda proti BINDu. Smyslel
jsem o panu DJB lepe...

V tom, ze hladky prechod na IPv6 neni nijak rozumne vyreseny, ma samozrejme
pravdu, jen jsem si nevsiml, ze by sam navrhoval lepsi reseni.

Ale tak jako tak to neni duvod k nepodporovani IPv6.

No a jsme u toho -- stejne si pak mnozi napisi preprocesor, ktery misto aby
generoval celkem ciste konkretni DNS recordy, generuje format pro jiny
preprocesor :-)

[Disclaimer: Nejsem zastancem BINDu, i kdyz ho uz leta pouzivam. Je to obluda
plna nejruznejsich certovin. Jenze djbdns se mi zda byt povestnym vyhanenim
certa dablem. NSD se mi libi cim dal tim vice, asi si ho pujdu vyzkouset.]

				Have a nice fortnight
